    The battery one is doing my head in. You cannot currently specify the low power chip. The choices are:

    1. Intel HD Lower power graphics
    2. Auto-switching.
    3. Hi-power NVIDIA GeForce

    Currently you can do 2 & 3, but you cannot do 1..... which is unfortunate!

    Hmm thats a worry - I presume you can switch it back after it all boots to the Intel one and if you use any apps that need the nVidia theyll use the switching properly?

    Wondering if its just a boot issue...

    Though being able to tell and save which programs should use which GFX chip in what circumstances (i.e. on battery) would be preferred if they can get it sorted to work automatically...

    It switches automatically back to the Intel once you stop using the app that forces the switch to NVIDIA.

    A choice of which to use would be nice I think.

    Westyfield2 - saw your post in the main thread but thought this concern warranted a new thread while its still being discussed. Your thoughts on the Windows bootcamp are interesting - might delay my purchase...

    Shirley its a software issue with OSX, I'll put a pound on that Apple is already testing a solution....I also bet under bootcamp Windows manages it better because the drivers have been out for a lot longer with regards of auto-switching?

    I don't see the Intel used at all on B/c - it's always the NVIDIA :confused:

    :(

    Suppose that's better than the other way round, but can't imagine it does the battery life any favours then!

    It estimates 4-5 hours in Win7 x64 via Bootcamp for me. To be fair I only use B/c for a couple of work specific apps that are quite intense so it could be you'd get longer.

    I find that skype turns on the 330!

    A little annoying when on battery.

    It needs some tweaking, but I've found the battery life to be brilliant, best out of all the laptops I've owned.

    Mind you, this is the first Macbook I've owned.. so that is probably why i'm so wow'd by the battery life.

    Yeah, i'm using it now. The force switching is good for the only one program that is randomly started up the GPU on me and that is the mac steam beta, other than that - Apples switching works fine without any other intervention.
